[the SWAT team escorting Barnes reaches the moving sidewalk on the Annex Skywalk] Chief Engineer Leslie Barnes: [on the phone with Trudeau] We're in the Annex Skywalk. I can see the array. I'll give you a call for protocol tests as soon as it's hot. That's all for now. [hangs up; we hear Barnes give an instruction to the SWAT team's sergeant. At the other end of the sidewalk, we see Sheldon set down his roller and start to reach for his gun] Sergeant: Right, sir. You've got it. [At the end of the sidewalk, O'Reilly presses the stop button that shuts down the walkway. All six of the men nearly lose their balance; he then turns his back to them] Sergeant: What the hell's going on? [to the worker at the end of the sidewalk] Sergeant: Hey! Put that back on! [as they continue along the walkway, Mulkey and Shockley start to reach for their weapons] Sergeant: Hey, asshole! Whadda I look like to you? [O'Reilly turns around, holding a Glock 17 in his left hand] O'Reilly: A sitting duck! [He shoots the Sergeant in the head, killing him instantly; he then dives for cover as the other officers return fire; McClane hears the gunfire from inside the ventilation shaft] John McClane: Shit! [He draws his Beretta 92FS and checks the slide] John McClane: Damnit! I hate it when I'm right! [He continues crawling along at a much faster speed]
